Analysis of bacterial sulfate-starvation responses and its application to waste water treatment

细菌的首选硫源是无机硫酸盐，因此^&lt；2-&gt；_4，但在某些环境中，硫酸盐可能不能自由获得。因此，几种土壤细菌已经发展出许多系统，允许使用各种有机硫化合物，这被称为“硫酸盐饥饿反应(SSR)”。通过对细菌SSR产生机理的控制，我们尝试开发了一种利用电子工业洗涤废水中的二甲基磺酸生产甲烷磺酸的工艺。

The preferred sulfur source for bacteria is inorganic sulfate, SO^<2->_4, but in some environments, sulfate may not be freely available. Thus, several soil bacterial species have developed a number of systems that allow the use of various organosulfur compounds, which is called "sulfate-starvation responses (SSR)". By controlling the mechanism of bacterial SSR, we tried to develop a methanesulfonic acid-producing process using the waste water containing dimethylsulfone, used for washing in some electronic industry.
